This happens in my application as well, dont know if its a known issue for boost python or not.. I too would like to see a solution; I myself have not had anytime to look into it since exceptions are a rare thing in my app. I can confirm however that a similar problem occurs on Solaris Sparcv9 machines, so I am guessing it has something to do with how solaris handles 64 bit exception handling. Something boost is not setup to handle I would suppose.
